Mr Porter has come under fire from the opposition and advocates for a federal integrity watchdog for using AAT appointments as a way to give former Coalition politicians and officials jobs.
A review of the tribunal by former High Court justice Ian Callinan, released in July 2019, recommended all appointments or reappointments to the tribunal should be lawyers qualified enough to be admitted to a state Supreme Court or the High Court, and “on the basis of merit”. The government is yet to respond to the review.
Mr Porter said on Friday “all of the appointees are highly qualified to undertake the important task of conducting merits review of government decisions”.
The other three full-time members he appointed, Rachel Da Costa, Namoi Dougall and Justin Gibbs are or have been lawyers.
John Rau, a former South Australian Labor deputy premier and attorney-general, was appointed as a part-time senior member. He is a barrister.
The new part-time appointments include Monash University forensics medicine professor Stephen Cordner, lawyers Genevieve Hamilton, Jessica Henderson, Angela Julian-Armitage and Naomi Schmitz, and a former senior immigration official Amanda Paxton, who has also sat on the migration tribunal.
Mr Porter has also promoted Fiona Meagher to deputy president and head of the tribunal’s National Disability Insurance Scheme division, and Karen Synon to deputy president and head of the social services and child support division. Both have been members of the AAT since 2015.
Ms Meagher has a legal background. Ms Synon is a Howard-era senator who has also served on the Refugee Review Tribunal and Migration Review Tribunal.
